Dear All, Ectoparasites control is really a dedicated effort...
, whether they are fleas or lice or ticks...if you manage to eradicate the parasites out of your pets, 95% more (eggs, larva, pupa) still able to survive in your furniture, household environment. Frontline COMBO spot-on would help to kill all stages through contact after 24 hours of administration...do not skip the monthly regime
If you find Frontline doesn't work anymore, you could switch to other product, to name Revolution 6% for cats...it contains different active ingredient which do same action - to kill adult + all stages parasites
To expedite the process of eradicating the parasites from in your environment, i would suggest the usage of insecticide such bayticol, taktic (amitraz) would be greatly useful, but must be used with caution since they are POISON...
use like every 2 weeks (our climate favors their breeding)
Good luck !!!
